How to Calculate Your FOV

Follow these steps to get the correct field of view for your sim racing setup:

1

Select Your Screen Type

Choose between single monitor, triple screen, or curved display. Triple screens require additional bezel and angle settings.

2

Enter Screen Size and Distance

Measure your screen diagonal and the distance from your eyes to the center of your monitor. Use metric (cm) or imperial (inches) units.

3

Copy Your Game Settings

The calculator shows both horizontal and vertical FOV values. Different simulators use different formats - copy the right value for your game.

4

Apply In-Game

Enter the calculated FOV in your simulator's graphics or camera settings. The exact location varies by game.

Features

Frequently Asked Questions

What is FOV and why does it matter?
FOV (Field of View) is the angle of the visible area your screen displays. Using the correct FOV is crucial because it ensures the on-screen perspective matches what you'd see in a real car. Wrong FOV can affect your depth perception, making it harder to judge braking distances and apex positions.
How do I measure my viewing distance?
Measure from your eyes to the center of your screen in a straight line. The most accurate way is to sit in your normal driving position and have someone measure, or use a tape measure. For triple screens, measure to the center screen.
Why are the values different for each game?
Some simulators use horizontal FOV (hFOV) while others use vertical FOV (vFOV). Additionally, each game may have different min/max limits. Our calculator automatically converts and formats the value correctly for each game.
Should I use the calculated FOV even if it feels zoomed in?
Yes! A correct FOV often feels "zoomed in" at first because we're used to artificially wide FOVs. Give yourself time to adjust - most drivers find their spatial awareness and consistency improve significantly after a few sessions with correct FOV.
What about ultrawide and super ultrawide monitors?
Ultrawide monitors (21:9) and super ultrawides (32:9) work great with correct FOV. Select your aspect ratio and the calculator will compute the appropriate FOV. These monitors provide more peripheral vision at the correct 1:1 scale.
How do triple screen angles work?
The side monitor angle is measured from the plane of your center screen. At 0°, the sides would be parallel to the center. At 90°, they'd be perpendicular. Most setups use 45-67° depending on the monitor bezels and mounting system.
